Project Information
  • Griffonia simplicifolia is a woody climbing shrub native to West Africa and Central Africa. It grows to about 3 m, and bears greenish flowers followed by black pods.
  • The seeds of the plant are used as an herbal supplement for their 5-Hydroxytryptophan content. 5-Hydroxytryptophan may be extracted from seeds as a supplement which as a serotonin precursor is beneficial in serotonin deficiency. Ongoing research suggests that 5-Hydroxytryptophan may also be beneficial in mood disorders including mild to moderate clinical depression and sleeping disorders.
  • Children with sleep disorder-related headaches seem to respond to 5-HTP treatment. It alleviates the effects of a variety of conditions, including depression, anxiety, insomnia and obesity.
  • 5-hydroxytryptophan is a more potent in vitro hydroxyl radical scavenger than melatonin or vitamin C.
  • 5HTP induced increase in salivary cortisol in panic disorder patients and healthy volunteers.
  • Effect of orally administered L-tryptophan on serotonin, melatonin, and the innate immune response in the rat.
  • For better sleep, consider Good Night Rx. 5HTP is not consistently effective when it comes to sleep, although using a lower dose of 10 to 30 mg may be tried one to three hours before bed.
  • 5-HTP should not be used in patients currently being treated or who have recently been treated with an SSRI antidepressant.
  • These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
